My strange brain. Part 1.

The first in a four-part series which looks at the lives of people with unusual neurological conditions. This part features Mohammed who suffers from narcolepsy and struggles to stay awake every second of the day. Similarly, Alana spends much of her time asleep. She has a very rare condition - Kleine-Levin Syndrome which affects the thallamus and hypothallamus and has taken away much of the last 4 years of her life. Mum to four Claire lost the ability to remember 25-30 years of her life following an infection from the herpes virus which entered her brain and wiped out her right temporal lobe. The same virus also destroyed much of Nicola's ability to remember but it affected her short-term memory so that she can no longer store new memories for longer than 2 minutes.
